I used one of our Light-O-Rama boxes we used last year for Christmas. They have 16 plugs and you can control them by using a computer to have a "Standalone" sequence, which basically means all you have to do is plug it it, and the box will do the sequence you program in it over and over again... And for my sign all I have is two strands of lights that alternate, so when the flash, it gives it an old marquee look to it... I couldn't be happier with how it came out!.

Let me know if you have any other questions, since this is my first year with a complete clown haunt, I figure we could learn together!.

I know you said the Light-O-Rama is easy to use but is it hard to get it to go with music? I like the sign by the way!
